Problems solved by technology

However, with the increase of the number of intelligent users, the time-varying power consumption quantity and random power consumption time of users will bring disturbances to the energy distribution at the load end.
On the other hand, the power supply end of the microgrid introduces a large number of renewable, energy-saving and environmentally friendly new energy sources, and the randomness of new energy also brings disturbances to the power supply management of the microgrid.

Abstract

The invention relates to a micro-grid power prediction method. According to the prediction method, generated power of a photovoltaic module of a micro-grid and generated power of a wind electricity module of the micro-grid can be predicted, the change condition of loads can be predicted, and based on the real-time detected energy storage condition of a storage battery module and the real-time acquired operation condition of a large grid, power supply strategies of the micro-grid are predicted, so that the micro-grid is in a safe, economical and customer-satisfactory operation state.

Description

Technical field [0001] The invention relates to a method for predicting power of a microgrid. Background technique [0002] As the global energy crisis continues to increase, low-carbon, clean renewable energy has become a research hotspot. At present, countries around the world have carried out research projects on micro-grids containing renewable energy. Microgrid refers to a network composed of multiple distributed power sources and their related loads according to a certain topology, and is connected to the conventional power grid through static switches. [0003] A large number of wind / solar distributed power generation is connected to the low-voltage distribution network as a two-way dispatchable unit in the form of a microgrid, forming a microgrid group or an active distribution network composed of multiple microgrids. However, due to the high randomness of renewable power sources such as wind power and photovoltaic power generation, the uncertainty of clean power so...
